Theoretical values for the branching ratios of the Z particle:
Leptonic decays |
Branching ratio |
2 neutrinos | 20 % |
2 electrons | 3,67 % |
2 muons | 3,67 % |
2 tau particles | 3,67 % |
Quark decays |
Branching ratio* |
Total | 69,9 % |
2 jets | ~ 40 % |
3 jets | ~ 24 % |
4 or more jets | ~ 6 % |
* Only the total branching ratio for quarks is a value from the Standard Model. The individual numbers of the branching ratios for events with different number of jets are experimental values.
